Testing across multiple agent systems reveals significant performance variation, with online RL succeeding primarily on ALFWorld while supervised learning pipelines dominate under fixed computational budgets.
A new arXiv paper argues that AI alignment cannot rely solely on stated principles because their real-world application requires contextual judgment and interpretation. The research shows that a significant portion of preference-labeling data involves principle conflicts or indifference, meaning principles alone cannot determine decisions—and these interpretive choices often emerge only during model deployment rather than in training data.
